Q. If my son file his own tax return as discussed, can I still be able to file as head of household?
A. Yes, because he is still your dependent.
A child filing his own tax return does not disqualify him from being his parent's dependent. In TurboTax, he indicates that somebody else can and will claim him as a dependent, at the personal information section. TT will check that box on his form 1040.
